Hello, It seems it's not an iPhone issue, because error message is: "pjsua_call.c Error initializing media channel: Require secure session/transport (PJSIP_ESESSIONINSECURE) [status=171142]" I believe you compile with srtp feature. You should investigate in this part. Regards Samuel > Message du 25/02/10 11:13 > De : "tech guy" > A : pjsip at lists.pjsip.org > Copie ? : > Objet : [pjsip] Calling issue on iPhone > > Hi All ?
